Specification forming part of Letters Patent No. 133,202, dated November26, 187i?.

To all whom it may concern:

Beit known that I, GEORGE S. BALL, residi ing at Dayton, in the countyof Montgomery and State of Ohio, have invented a certain Improvement inGrain Drills, of which the following is a specification:

This invention relates to that class of graindrills in which the hoesmay be arranged either in a straight or in la zigzag line; and my imiprovement consists in the employment, in combination with an oscillatingbar, to which the changeable hoes are connected, of one or moreperforated bars fixed to the frame-Work of the drill, and acorresponding number of movable bolts on the oscillating bar, soarranged as to enter the perforations in the xed bars, for the purposeof locking the oscillating bar in `any required position to the saidfixed bars.

It further consists in the combination, with said locking devices, of asystem of levers so disposed that, by means of the hand or foot leverthereof, the oscillatin g bar may be iirst unlocked and then shifted toits new position.

Figure lis a bottom view representing so much of a grain-drill as isnecessary to clearly illustrate my invention. Fig. 2 is a transversesection thereof. Fig. 3 is a transverse section of the oscilla-tin g barat a point where it is provided with a looking-bolt.

The same letters of reference are .employed in all the figures in thedesignation of'identical parts.

The changeable hoes are carried by a series of drag-bars, A, andalternate with the unchangeable hoes, which are connected by thedrag-bars B to the fixed crossbeam B of the frame of the drill. Thedrag-bars A are hin ged to the oscillating bar C, which is supported byits journals in suitable bearin gs upon the frame, and, in the exampleillustrated, moves over the two ixed metal bars D D, which are curved tocorrespond with the arc described by the under side ofthe oscillatingbar (l in advancing or retiring the changeable hoes. Opposite to each ofthese' bars D a bolt, E, is arranged in the oscillating bar G, saidbolts being intended to enter the perforations d in the bars D to lockthe oscillating bar when the changeable hoes have been arranged inproper relation to the unchangeable ones.

The bolts are projected by spiral springs e, and are provided withlaterally-projecting studs, e', Which extend, respectively, into eyes inthe ends of the levers F and F. These levers turn upon the fulcrums fiand f1, and are pivoted together at f2, from which point the one markedF is bent downward, such bent end being linked to the arm or crank g ofthe swivel-bolt G, which is arranged in a pendant, G, fixed to the lowerside of the oscillating bar C. Thefbolt G is fastened to tho rod H,which extends toward'the drivers seat v andterminates in a handle, H.

In shifting the changeable hoes, the operator first gives a partialrotation to the rod H, whereby the locking-bolts E are retracted anddrawn out of the perforations in the bars D, and then pulls or pushesupon said rod to oscillate the bar G.

What I claim as my invention, and desire to secure by Letters Patent,is=

l. The combination ofthe Oscillating bar C, fixed perforated bars D, andlocking-bolts E, substantially as and for the purpose specified.

2. The combination of theoscillating bar C, fixed perforated bars D,locking-bolts E, levers F F', cranked bolt G g, and rod H, substan tially as and for the purpose specied.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
